Overfeeding in flower, Flushing in Coco Coir

That is way too strong. You are giving 3.5 combined right? Not of both. As I don't think that such high dose is good, clearly it wasn't. And that extra .5 wouldn't do much you'll need to cut them even more and focus on bloom nutes. It's not soil. So a hard flush and then you can go back to feeding with nutes the next day. After every feed that day water should follow behind your nute feed, doesn't even have to be run-off just enough to come behind the nutes to flush out residue/salts. When you say smell funny what do you mean? That might be down to RH as I had this problem when RH was 70% in my tent the zkittlez I just harvested had like a funky mold smell, I scanned thru the entire plant no mold. Go my RH down to 57% for the last 2 wks and the smell was gone after a wk, would it be humidity, as overfeeding wouldn't really have an impact and canna products espically as they are organic right? Feel free to DM me.
